Yesterday was World IPv6 Day. From the German perspective, there was a huge spike in traffic-increase on that day. Not so much as one might have expected, but still a significant increase:

IPv6 Traffic at the German Internet Exchange

Interestingly, although IPv6 day is over, the traffic didn’t decrease. For the fun, I checked with youtube.com – and it’s still serving traffic in IPv6!

Now compare to the the montly stats:

DE-CIX monthly IPv6 traffic

Nethertheless, IPv6 traffic is still very little compared to regular IPv4 traffic:

IPv4 Traffic at DE-CIX

So while IPv6 peaked with 1.8 Gbit/s, IPv4 at DE-CIX is still a 3.2 TBit/s. Which is about 2000 times more traffic.

But what does that tell us?

Thinking of the IPv6 traffic stats I derive the following things. First, I assume that IPv6 day didn’t make user migrate to IPv6. I think – although I can’t prove it – that existing IPv6 users kept using the Internet like they used to.

But the statistics tells us one thing: That a lot of people were prepared and ready – the early adopters. Since youtube.com is still online with v6 – and the traffic didn’t change to much – I think that either youtube.com made up most of the v6 traffic, or, that most of the websites are still live with v6.
